Data centers use liquid to cool servers and other important equipment to prevent damage and reduce down time. Heat exchangers are used to remove heat from the liquid and recirculate it back to the servers. One method to remove heat is through the use of ambient outdoor air. Ambient air temperature must be monitored to ensure an optimal heat transfer. The Rosemount™ Synchros™ Temperature Monitor is a user-friendly way to monitor the temperature of the air that is blown across the heat exchanger coils.
